Explain whether the data values could fit to a normal distribution to estimate population percentages.
A) The data values could not fit to a normal distribution because the distribution is skewed right. The data value of 7
is much greater than all the other values.
B) The data values could fit to a normal distribution because the distribution is skewed right with an outlier of 7
.
C) The data values could not fit to a normal distribution because the distribution is skewed left. The data values of 0
are much less than all the other values.
D) The data values could fit to a normal distribution because the distribution is symmetric with a peak at its mean of 3.
